| 17:44 | Add the lsmode(MODE) function in the fileio.c extension and use that function in the .archive implementation. Add the --append and --dryrun options to the .archive command and remove the --zip option, making it automatic. check-in: 38f28029 user: drh tags: trunk | |
| 17:37 | Return an SQLITE_CONSTRAINT error if an attempt is made to insert duplicate entries into a zip archive. check-in: 1f099b2b user: dan tags: trunk | |
| 16:30 | Have the zipfile module automatically append "/" to directory names that do not already end with such a character. This is required for info-zip compatibility. check-in: 94bc3c60 user: dan tags: trunk | |
